MEANS FOR SECURING ANTISKID CHAINS T0 VEHICLE WHEELS.

Leeann.

To all whom it may concern: I

CARL AQKERBERG, a citizen of the United States, and resident of "Oshkosh, in the county of Winnebago and State of \Visconsin, have invented a certain new and useful Improvement in Means for Securing Antiskid :Chains' to Vehicle lVheels,

of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to improvements in means for securing anti-skid chains to vehicle Wheels andthe method of making same. The objects of my invention are:

First. To provide means forsecuring anti-. skid chains to wheels, comprising a pair of hooks and means for securing the hooks to a vehicle wheel, so that the shanks thereof eX-.

tend transversely of the wheel, and in spaced parallel overlapping relation, with the shanks of the two hooks extending in opposite. di-

rections, whereby slack in the chain will be.

' distributed between the two hooks, thereby from becoming ter described, comprising a pair-of hooks sotending to prevent the ends. of the chain v V M chains to a vehicle-wheel comprises a plate .13, which is curved bothlongitudinally and transversely'to conform to the co'ntour of the inner side of'the telly 10, and provided detached from the hooks;

Second. To provide means of the characdisposed relatively to each other that when an anti-skid chain isengaged withthe bight of one hook, an adjacent portion of the other hook will prevent the other end of the anti-skid chain from being detachedfrom.

the other hook; l

Third. To providea device of the character described, comprising two hooks so. located relatively to the wheel asto be protected from contact'with curbs and other obstacles, and tending-to prevent the chain from becoming entangled the brake mechanism or in the'chain driving gear in'the 1 event the anti-skidchain becomes.- broken;

- and Fourth. To provide a'device of the character described, which is economical to manufacture and'easy to operate.

Other objects will appear as this descrip had to the,

tion progresses, reference being accompanying drawings,-in which Figure of a metal wheel, showing my improved device in use for connecting an anti-skid chain. to the wheel; v

Figure 5 is an end view of the construction shown in Figure 3, with the links removed; and i V Figure 6 is aplan view of a blankillustrating the method-by which I form my improved device. I v j i v i Throughout the several vievvs similar reference characters will be used, forireferring to similar parts i i [character 10 indicates theho llow any of a' metal wheel, which is equipped with a rim l1 and a double tire 12. The details ofthe wheel, construction are merely illustrative,

and form no part of my present invention.

My improved device for securing anti-skid .and 16 of .whichare formed integral .with

the opposite sides of the plate 13,. and the shanks 17 and 180i which. extend inspaced parallel overlapping relation across the plate .in oppositezdirections. The free ends of the shanks 17,-and 18 are each provided with a crossh'ead 19 and 20, respectively, extending in fae plane substantiallyparallel withthe lane of the plate 13. From an inspection of Figure Git will be noted that the free ends of the shanks arebent downwardly toward the plate. It will also he noted from an inspection of Figure 3 vthat the bight of each hook extends outwardly beyondthe crosshead of the adjacent-hook. This construction permits easier manipulationof the links.

of the auto-skid ohainover the crossheads than would bethe case if the crossheads occupied a ,position immediately adjacent the bights. of the respective hooks.

Referring 3130 the drawings, the reference While I do not wish to limit my invention to any particular spacing of the two hooks relatively to each other, it will be noted from an inspection of Figures 3 and 4 that I have provided means whereby there is a tendency for one endof the chain tolock the other end of the chain to its hook, and thereby prevent accidental detachment of the chain, and especially so in the event the chain becomes broken or'worn through.- It will be noted from an inspection of these figures'that with the link 21' in the bight 15, the space between the end portion 22 of the crosshead 20 and the adjacent portion of the link 21 is too small to permit the link 23 to pass therethrough. This does not, however, prevent either end of the chain from being detached from its hook, for it will be seen that"when,say, for instance, the link 21 is shifted so as to be brought into contact with the shank 17 at a point intermediate its ends,

there will be'plenty of room for the link 23 tobe passed over the crosshead20 and be- "tween 'it and the bight 15 of the other hook.

V of the stock from which the chain links are It will of course be clear-that if the diameter 'Inade is'reduced o'r if the spacing between adjacent portions of the hooks is increased,

this locking function will disappearto a greater or a lesser extent, but there will nevertheless, with practically any desiredspacing of the hooks, be more or less inter-r ference between the ends of the chain as they 1 move first in one direction and-then in the other to prevent any accidental detachment ofthe chain from the hooks, even though the a chain becomes. broken; forit will be noted that, by theuse of the crosshead, I have providedmeans which makes it necessary to 40' bring the link of the chain which is engaged with any one of thehooks into a certain predetermined position'before it canbe detached therefrom, and it is highly unlikely that with the interference which does exist between the two ends of the chain the end link should "accidentally attain this position.

forming die.

In forming my improved device themetal is first broken down to prepare it-for the The metal is then subjected to the forming dies, which results in a blank similar to that shown in Figure 6, in which the shanks 17 and' 18 lie substantiallyinthe 'plan'e oftheplate 13; At this stage in the process, the openings 14 have not been formed. The blank is'then punched to form J these openings, and the plate 13. is then 'bent to conform to that portion ofthe wheel folly to whichityis to be attached.

' The next step in the process is to bend the. shanks 17 and 18 up out of the plane of the plate '13, around substantially the axes w-m.

fThis brings the cross heads 19 and 20, which previously extended at right angles to the 7 plane of the platej13, into substantial parallelism therewith, and the free ends of the other adaptations and modifications within the scope of the appended claims.

I claim is:

1, Means for securing an anti-skid chain toa vehicle wheel, comprising a plate having a hook at each side thereof, the-bights ofs'aid hooks being'formed integralwith said plate Having thus described my invention, what opposite directions in spaced substantially parallel overlapping relatiomand crossheads secured-t0 the free ends of said shanks and each lying in a plane substantially parallel to the plane of said plate,'the bight of each,

and the shanks of said hook extending in hook lying outwardly beyond the. crosshead of the adjacenthook. e 2. Means for securing an anti-skid chain to a vehicle wheel, comprising a plate'having a hook at each side thereof,,t,he bights of said hooks being formed integral with-said plate and the 'shanksofsaid hook'extending in. opposite directions in spaced substantially parallel overlapping relation, and crossheads secured to the free endsof said shanks and each lying in a planesubstantially parallel to the lane of said'plate 3. cans foresecuring an anti-skid chain to a vehicle wheel, comprising a plate having a hook at-each side thereof, the bights of said 7 hooks being formed integral with said plate and the shanks. ofsaidhook extending in opposite directions in, spaced substantially parallel overlapping relation I I 4;. The combination with ayehicle wheel,

of a plate, means for securing said plate to a wheel, a hook at each side of said plate, formed integral therewith, the shanks of said'hooks extending in opposite directions 'in'spaced parallel relation, and,

provided at their freeends with crossheads, and" an anti-skid chainihaving one end engaged over one of said hooks and theother end-engaged: over theother hook, the space between each crosshead and-the adjacent portion of the other hook beingjless than the I combined diameters ofzthe linksof said chain engaged with saidv hooks; I

5. The combination with ave'hicle wheel,

of a, plate, means for. securing said plate to wheel, a hookat ea'chsid'e of said ,plate,

formed integral the'rewith,the shanks of said hooks extending in opposite directions; in spaced parallel relation, and an anti-skid chain having one end engaged over one of said hooks and the other end engaged over the other hook, the space between said hooks at one end being less than the combined diameters of the links of said chains engaged with said hooks, and the space between said hooks at any other point being greater than the combined diameters of the links of said chain engaged with said hooks.

6. In combination with a wheel, a hook with its base on one side of the inner surface of the wheel and its length across the rim thereof, another hook parallel to the first hook with its base located diagonally opposite the first hook, the bodies of said hooks being projected in opposite directions parallel to one another and spaced apart, with the heads of said hooks having their free ends overlapping.

7. The combination with a wheel, of a base on the inner side of the rim of said wheel, a pair of hooks with their bases diagonally opposite to one another and their free ends overlapping, located on said base. substantially parallel to one another, means co-operating with said hooks to prevent a chain,

ends located parallel to one another projected in opposite directions and. overlapping, with the bases of said hooks located diagonally opposite on said detachable base.

9. In combination with a wheel, a detachable base on the inside of the rim of said wheel curved longitudinally and transversely so as to conform thereto, a pair of hooks ad;- jacent to andpaiallel with one another located upon said base, their bodies projecting in opposite directions and on a line at an angle to the main axis of the hub, their free ends overlapping and chain retaining knobs on said free ends.

In witness whereof, I hereunto subscribe my name this 19th day of March, 1920.
